TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Feb. 11, 1908 Application filed March 26.1906. Serial No. 307.993.

To all whom it may concern:

Be it known that I, GnAnLEs L. FoRTIER, a citizen of the United States, and a resident of Milwaukee, county of Milwaukee, and State of lVisconsin, have invented certain new and useful Improvements in Type- VVriting Machines, of which the following is declared to be a full, clear, and exact description.

The invention relates to type-writing machines, particularly to tabulating mechanism therefor.

The improvement provides a simple con struction for tabulating work without employing the letter-spacing escapement therefor and also provides a light carriage for this work that will start and move rtuickly but which may be arrested with litt e shock or jar, without the use of brakes, dash-pots or other retarding devices, to thereby increase the life of the machine and increase the rapidity with which tabulating work may taken on line 11 of Fig. 2.

forms.

be done.

With these and other objects in view the invention consists in the features of construction, combinations and arrangements of parts hereinafter set forth, illustrated in the accompanying drawings and more articularly pointed out in the appended 0 arms.

The invention is more particularly ada ted for and is shown applied to a machine 0 the so-called visible or "front-strike ty e, although it may be readily adapted to ot er In the drawings Figure 1 is a longitudinal section of the machine to which the present improvements are applied, the section being Fig. 2 is a rear view of the ,machine with certain parts broken away. Fig. 3 is a detail section on the line 33 of Fig. 1. Fig. 1 is a detail plan view with certain parts shown in section on line 44 of Figs. 1 and 2.

The key levers 10 are mounted as usual in horizontal series in the base portion of the machine frame 11. The levers are ivoted at their rear ends u on a common ulcrum ledge 12 and their 'orward' upturned ends are provided with finger pieces or keys 13. Springs 14 normally uphold the key levers against a transverse stop-bar 15. Typebars 16 (oneonly of which is shown) are pivoted upon a segment 17 to strike upwardly and rearwardly against the front of the platen 18 and suitable links connect the key-levers and type-bars. The type mechanism described may be of any usual or .desired construction.

To provide means for tabulating with ease and rapidity and without shock and jar u on the parts of the machine, the paper-holding means or platen is mounted upon a light supplemental carriage which, in turn, is connected to and is preferably mounted to slide upon a main carriage that is provided with one member of the letter spacing escapement and with the other appliances usually mounted upon the tabulating carriage. The main and supplemental carriages are connected and normally shift together for ordinary work, but in tabulating the light supplemental carriage may be released from the main carriage for quick shift to the proper columnar position. Inasmuch as such a supplemental carriage is much lighter than those usually employed, it will have less inertia and may be quickly moved by a comparatively light spring and will be arrested with little shock or jar upon the parts of the machine, and it is not necessary to release the letter-space escapement.

The main and supplemental carriages may be of any suitable or desired construction.

In the form shown, the main carriage comprises the front and rear bars 20 and 21 connected by the side bars 23. The rear bar 20 of the main carriage (see Figs. 1 and 2) is provided with downwardly projecting perforated lugs 24 through which extends a guidebar or rail25 that is fixed at its ends to a pair of brackets 26 projecting laterally from the upper rear portion of the machine frame. The front bar 21 of the main carriage in the form shown," is provided with a pair of central depending lugs 27 (see Fig. 1) between which is mounted a roller 28 that engages a cross rail 29 on the front of the machine frame. The side bars 23 of the main car' riage are provided with depending circular or loop-shaped portions so that they do not interfere with the independent shift of the light supplemental carriage.

The supplemental carriage comprises the side bars 30 connected at their rearends by a longitudinally extending rod 31 and at their forward ends by the platen supporting shaft 32. The bar 31 of the supplemental carriage is provided with dependin lugs 33 (see Fig. 3) and preferably adjustab y secured thereto by screws 34. The lower ends of the lugs are in the form of perforated. ears .and engage a rail or guide-rod 35 that is fixed at their opposite ends to a lug 36 and to a laterally extending bracket 37 on the side bars 23 of the main carriage. An adjustable stop or collar 38 upon the guide ortrack-b ar 35 of the main carriage is arranged to engage one of the lugs 33 of the supplemental carriage to limit the return movement of the supplemental carriage with reference to the main carriage. The supplemental carriage however, may be moved in letter-space direction independently of the main carriage, and to permit its full shiftin such direction, one end of the track or guidebar 35 is connected to the laterally extending bracket 37 on the main carriage. The supplemental carriage is also provided with a U-shaped frame bar 39 extending beneath the platen and connected. at its ends to the side-bars 30. This U-bar is provided with a central roller 40 that engages the track-bar 41 that is vertically shiftable and mounted centrally upon an upright 401. This upright is mounted on its lower ends upon a pair of rock arms 402 that extend forwardly therefrom and are journaled at the forward ends in a bracket 403 depending from the segment 17. The lower arm is mounted on a rock shaft 404 that extends from the side of the machine frame and is provided, preferably at each end, to the rock arm 405 connected by a link 406 to a suitable shift key. By this means the supplemental carriage maybe shifted. vertically, swinging about the rod 35,'for printing upper case letters. The longitudinal bars 31 and 39 of the supplemental carriage serve to support the guide plate 42 and other paperguiding and holding means. A line-space lever 43 is provided with a spring-pawl 44 arranged to engage the teeth of the ratchet 45 on the end of the platen. The construction and arrangement of the main and supplemental carriages may be widely varied, as desired, from that set forthwithout departure from the essentials of the invention.

A spring-actuated propelling drum 46 of usual construction is mounted on the stud shaft 47 at the back of the machine frame, and is connected by a drive-strap 48 with an arm 49 that is connected to and depends from one of the side bars 30 of the supplemental carriage. This drum may be of sufficient power to propel both carriages, but preferably a second drum 50 mounted. on the stud 51 is connected. by a strap 52 to an arm 53 connected to and depending from one end of the rear bar 20 of the main carriage.

A suitable letter-space escapement mechanism is arranged to cooperate with the main carriage. In the form shown this mechanism comprises a rack 54 extending liietween the rear ends of the side bars 23 of the main carriage and a rocker 55 provided with dogs 56 engaging the rack 54. I The rocker is mounted upon a bracket 57 fixed to the rear portion of mares the machine frame and is connected. by a link 58 to the universal bar 59 extending beneath the key-levers 10.

The main and. supplemental carriages are normally connected by suitable releasable devices for tabulating escapement compris ing a rack 60 mounted. on. one of the can riages and a dog 61 for engaging the rack mounted upon the other carriage. 111 the form shown, rack 60 is pivoted. in. upright position upon the rear bar 20 of the main carriage. The pintles of the rack are provided with stop pins 62 for engaging lugs 63 (see Fig. 2) and springs 64 (see lig. 1) lixed to the side bars of the main carriage normally uphold the rack 60 in vertical position with the stop pin 62 in engagement with the lug 63. The teeth of the rack 60 are bev eled and the dog 61 is of a one-way yielding spring-held type so arranged that independent movement of the carriages in letter-space direction is prevented when the rack is in. engagement with the dog. But the supplemental carriage may be returned independ ently of the main carriage as dog 61 will then pass idly over the teeth of the rack 60 until the lug 33 on the su plemental carriage en: gages the stop or collar 38 on the main carriage.

Suitable means are provided for shifting the rack to disengage it from the dog, such means comprising a shiftable member in. the form of a bell lever 65 that is pivoted to the bracket 57 on the rear of the machine casing and projects upwardly through a slot therein. At its upper end the shiftable .member 65 is provided with a forwardly extending abutment 66 that is arranged to engage rack 60 and shift it against the tension of its spring 64 out of engagement with the dog 61 so as to release the supplemental carriage and permit its free run in letter-space dirc tion under the influence of the propelling drum 46. The shiftable bell lever 65 is actuated by a tabulating key lever 67 mounted within the base portion of the machine frame and pivoted on the fulcrum 12 of the type-bar key-levers. The tabulating keylever 67 is connected to the bell-lever 65 by a link 68. This key-lever is cut away (see Fig. 1) above the universal bar 59 so that its movement will not operate the letter-space escapement but will serve merely to release the tabulating escapement formed by the rack 60 and dog 61 to permit the free run of the supplemental carriage.

Any suitable form of tabulating mechanism may be employed for arresting the run. of the supplemental carriage. In the form shown, the supplemental carriage is provided with a stop supporting bar 69 having a series of openings 70 within which the column-stops 71 may be set or adjusted in. any desired position. The stops 71 are prefer ably provided with shank portions 72 that fit snugly within the hole 70 to securely hold the stops in place upon the bar 69. Bar 69 is, as shown, arranged above the rack 60 on the main carriage and the dog 61 that en gages the rack 60, is conveniently mounted at one end of the stop supporting bar 69, as shown in Fig. 2.

Thedog 73 for cooperating with the column-stops, is conveniently mounted on the shifting belllever 65 so as to be moved therewith into the path of the column-stops when the tabulating key-lever 67 is depressed. The spring 74 (see Fig. 1) engages the belllever 65 and normally holds the dog 73 out of the path of the column-stops 71 and the abutment 66 in such position that the rack 60 of the main carriage may-engage the dog 61 on the supplemental carriage.

When the tabulating key-lever is depressed, the rack 60 is disengaged from the dog 61 to permit the free run of the supplemental carriage and at the same time stopdog 73 is projected into the path of t e column-stops 71 so that the supplemental carriage will be arrested in proper columnar position. By reason of the light weight of the supplemental carriage, it will start and move easily and quickly and will be arrested withoutshock or jar upon the parts of the machine. The life of the machine and the rapidity with which tabulating work may be done is thus materially increased since it is unnecessary to employ brakes, dash-pots or other retarding devices which, although they may check somewhat the shock and jar upon the machine parts, materially decreases the speed at which the tabulating work may be done, Moreover, inasmuch as only the light supplemental carriage is shifted, when tabulating, the propelling drum 46 therefor may be provided with a comparatively light spring. In ordinary work, both carriages will be propelled by the drums 46 and 50 that will have springs of suflicient combined strength for this purpose. It will be noted that the letter-space feed is not released for tabulating work.

To gradually check the movement of the supplemental carriage when released, the stop-dog 73 is preferably pivoted between ears or lugs 75 (see Fig. 2) on the side of the bell-lever 65, and a spring 76 normally holds the main portion of the dog away from the belllever but with the tail-portion 77 of the dog in engagement therewith. hen one of the column-stops 71 engages the dog 73, it will move it in letter-space direction until the dog is arrested by its engagement with the bell-lever 65. As this movement of the dog is against the tension of the spring 76, the latter will serve to gradually bring the supplemental carriage to rest without shock or ar.

Suitable means are preferably provided to prevent the rebound of the supplemental carriage when one of the column-stopsis brought into engagement with the stop-dog 73. For this purpose, the upper end of the bell-lever 65 is provided with a horizontally disposed pivoted pawl 78 (see Fig. 4) which, when the bell-lever is projected forwardly is arranged to engage inclined ratchet teeth 79 on the lower portion of the rear face of the stop sup porting bar 69. This dog and the ratchet teeth are so inclined that the supplemental carriage may freely move in letter-space direction, but any backward movement or rebound after one of the column-stops engages the stop-dog is prevented.

It will be understood that the teeth of the racks 60 and 79 are spaced apart in correspondence with the teeth of the letterspace rack 54, the teeth of the latter of course corresponding with the different letter-space positions of the main carriage, as indicated by the scale or pointer 80 and 81 at the front of the machine.

To securely hold the stop-dog 73 in proper position, the bell-lever that carries the dog is arranged to swing between a pair of lugs 82 and 83 on the back portion of the machine (see Fig. 2). The lug 83 extends upwardly and engages the upper portion of the belllever 65 on the side opposite the stop-dog 73, so that the impact of the dog against the bell-lever 65 is taken up by the lug 83.

It will be noted that the rack 54 and the dogs 56 on the rocker 55 form the ordinary letter space escapement, While the rack 60 and dog 61 form a separate, independent tabulating escapement. With the ordinary tabulating devices the free run of the carriage is effected by releasing the letter space escapement. In the present device the letter space escapement is not shifted or released, but the free run of the carriage or paper carrying devices is permitted by releasing the supplemental tabulating escapement that is entirely separate and inde pendent of the letter space escapement.

It is obvious that the details set forth may be widely varied without departure from the essentials of the invention.
